Implementation of Continuous Descent Approach in Airports with Medium Traffic Density. The continuous descent approach, also known as the “green approach”, is a set of operational approach and landing procedures, designed to minimise overall noise exposure and polluting gas emissions.
The project has already been successfully implemented in many airports in the Aena network, and was made possible by Aena's partnership with the Public Body ENAIRE and CRIDA (Reference Centre for Research, Development and Innovation in ATM) and the participation of Air Europa, Boeing (BR&TE) and INECO.
Phasing in the use of renewables, such as the implementation of mini wind turbines and photovoltaic power plants for self-consumption in Aena network airports, in order to help reduce greenhouse gas emissions and fossil fuel consumption.
In line with its Energy Saving and Efficiency Plan, Aena is carrying out various actions in its terminals and airport facilities to optimise power consumption through energy efficiency and the use of renewable energy. These include:
- Adjusting energy consumption to real airport operations, through measures such as adjusting how long information screens and check-in desks are running.
- A general lamp replacement plan based on more efficient technologies.
- More efficient heating and cooling methods, such as protocols for natural ventilation and pausing climate control equipment, and the use of automatically controlled systems.
Aena ran a pilot project in 2011-2014 to assess the viability of using electric vehicles in and around airports in Adolfo Suarez Madrid-Barajas, Barcelona-El Prat, Palma de Mallorca and Lanzarote airports, with a total fleet of 26 electric vehicles with an associated telemetry system to provide real-time data on the vehicles for analysis. Additionally, 53 recharging stations were installed in the airports taking part in the pilot scheme.
After this experience, Aena now has 13 electric vehicles in use in various airports in the network and plans to gradually replace traditional internal combustion vehicles used in normal engineering and maintenance work, operations, environmental work and other areas of airport activity.
A joint project by Aena, Iberia and Algaenergy that is equipping Adolfo Suárez Madrid-Barajas Airport with an experimental technology platform with the main goal of making biofuels from microalgae.
This experimental technology platform is the most modern and powerful R&D tool to date in microalgae biotechnology, and will grow different species and experiment with their behaviour and performance in order to later scale up the results to an industrial level.
